The influence of extraneous supplementation of L-ascorbic acid in chronic chlordane toxicity has been studied in rats. Oral administration of chlordane brings about a marked growth retardative effect, stimulates vitamin C synthesis in the system, elevates the vitamin C status of the liver and kidney tissues and also the urinary excretion. It inhibits the activities of acid and alkaline phosphatases, SDH and Mg2+-ATPase of both hepatic and renal tissues. The activities of serum and mitochondrial GOT, serum alkaline phosphatase, and glucose-6-phosphatase of both hepatic and renal tissues are markedly stimulated. The normal histological patterns of both liver and kidney tissues are grossly altered under chlordane toxicity condition. There occurs marked increase in the hepatic lipid composition. Supplementation of L-ascorbic acid in high doses to the chlordane treated rats can effectively counteract some of these alterations in respect of enzyme activities, morphological characteristics and of hepatic lipid composition.

is a tropical wild edible plant that is locally consumed in the Southern Nations, Nationalities, and Peoples Regional state of Ethiopia. However, there is limited information comparing nutritional, phytochemical, and anti-nutritional factors present in fruit pulps and seeds of the fruit. Therefore, this study aimed to investigate and compare the proximate compositions, phytochemical constituents, and anti-nutritional contents of the fruit pulp and seeds.

Background: Surgical methods of gingival depigmentation can be challenging, particularly if the gingival phenotype is thin due to the risk of gingival recession and bone exposure. Thus, exploring alternative, non-surgical, minimally invasive treatment modalities is warranted. In dermatology, vitamin C is extensively used for depigmentation and microneedling for collagen induction, with limited literature about its usage for improving gingival esthetics.

This study is focused on the design, synthesis, and evaluation of some sulfonamide derivatives for their inhibitory effects on human carbonic anhydrase (hCA) enzymes I, II, IX, and XII as well as for their antioxidant activity. The purity of the synthesized molecules was confirmed by the HPLC purity analysis and was found in the range of 93%-100%. The inhibition constant (K) against hCA I ranged from 0.
